Hi Jennifer,
Thank you so much for visiting the Disney Parks Moms Panel with your question. I love that you are looking for something fun and outside of the theme parks as a surprise for your family. I have a few ideas for you.
If you are all up for some great outdoor physical activity, consider the
Wilderness Back Trail Adventure. On this two-hour tour, you will learn to ride a Segway X2, and then will explore Disney's Fort Wilderness on the Segway X2. I did this tour recently, and it was a lot of fun! It was great to learn how to ride the Segway X2, and then to glide around Disney's Fort Wilderness and learn more about this amazing resort.
For a less active experience, you could all take a ride in an Amphicar at
The Boathouse Restaurant at Disney Springs. These unique vehicles appear as classic cars, but head into the water for a ride! Be sure to stay and sample some of the tasty fare at this new restaurant.
Finally, for a fun treat that the whole family can enjoy together, consider a
fireworks cruise. On a fireworks cruise, your family will be on a boat with a cast member guide who will take you on a ride and then stop with a fabulous view of either IllumiNations: Reflections of Earth or Wishes Nighttime Spectacular. I have experienced both of these, and to see the fireworks from the serenity of a boat is truly magical. Please do note that fireworks are weather permitting.
I hope that this gives you a few ideas, Jennifer! Have a great time planning your magical vacation, and please do let us know if you have any further questions.
